Ive seen various posts regarding internal pressure for our bosch pumps;1000rpm engine - 43.5psi2000rpm engine - 75.4psiThese are apparently the optimum pressures for efficient operation of the dynamic advance system.My question is; are these figures for all bosch ve pumps? I know these figures are for VW Golfs etc but will they apply to my Peugeot 306?Another question; ive set my pressure at 1000rpm at 43.5psi but it only reaches mid 60psi when getting to 2000rpm. Is there a reason for this? A defect in some part of the pump?Thanks,Anton
Mark it is a pump from a 1.9 turbo diesel peugeot 306. Would this alter your original answer?Also what is SAE?
Mark here are the numbers for my bosch pump;0 460 494 370It was originally a 9mm pump as you can see. Ive since swapped in an 11mm pump head, plunger and collar from a ford transit.Camplate is Peugeot 306, cant remember what the return springs are but the internal pressure valve is still Peugeot 306.Ive also increased the advance piston travel by shaving a few mm from the advance piston.
Surely plunger lift will not have changed as i am using the Peugeot camplate?
Not sure what the standard lift is Mark.Can i measure it through the timing hole or measure it off the camplate?How would the lift effect the advance system?
